The ultrasound is also helpful to make the diagnosis of a variety of soft tissue tumors bacause of its safety, low cost, non-invasiveness and usefulness. We analysed ultrasonographic findings of 43 cases of soft tissue tumors which were histopathologically confirmed by biopsy and obtained the following results. The ultrasonography could effectively image not only the presence, size and location of the lesion, but also the relationship between the lesion and the adjacent structures. And this method could easily identify the consistency of the lesion, solid or cystic nature, be used to guide the percutaneous biopsy and aspiration without exposure to radiation, and afford the differentiation of malignant lesion from benign one. It could also define the eritities of soft tissue tumors by the nature of internal echo, margin of the lesion, internal echo homogeniety, post-acoustic enhancement, and so on.

The purpose of this study is to make an emphasis the necessity of the dynamization after interlocking intramedullary nailing. We reviewed 75 cases of the fractures of the shaft of femur or tibia fixed with static interlocking intramedullary nailing. We excluded the cases in whom the locking screws were removed for the purpose of the relief of pain from the irriataion by those screws. The parameter we reviewed were the type of fracture, postoperative gap between the major fragments. Early callus formation, the union time, postoperative dynamization and controlled weight bearing. In those cases in which the contact surface between the major fragments was more than 50% and there noticed no early callus within 6 weeks after operation, the union time was shortened after dynamization, when the contact surface was less than 50% and there noticed no early callus, the union time was shortened after bone graft and dynamization which resulted in some shortening in the length in acceptable ranges. In cases with a major gap of more than 2mm, the union time was shortened after dynamization. The rate of early callus formation was a little higher in cases with postoperative controlled weight bearing than those to whom we did not permit a controlled weight bearing.

The “delta phalanx”, first named by BlundeII Jones in 1964, is a triangular(“delta-shaped”) or trapezoidal phalanx with C-shaped epiphyseal plate causing progressive angular deformity of the digit with growth. Neither splinting nor physical therapy is effective in improving the condition. Surgical correction is indicated and several methods of correction have been reported. Authors have experienced a rare case of “delta phalanx” occuring in the proximal phalanx of the syndactylous digit.

Fourty one cases of open fractures of tibial shaft complicated with varying degrees of soft tissue injuries were trested by one-plane unilateral external fixation with AO fixator. In seventeen csses among them, interfragmental lag screw fixation was applied in addition, for more rigidity and stability of the fixation. All of thern were followed up at least for one year and we obtained the following results. 1. Rigid stable external fixation provided by additional minimum internal fixation may not increase the rate of infection but rather enhance prompt primary bone healing. 2. One-plane unilatersl external fixation may facilitate good access to the wound for subsepuent reconstructive procedures, and enhance pain-free early full range of joint motion, thus promote early bone union. 3. Comparing with bilsteral fixation, there wss almost no difference in the union time of the fracture even with one-plsne unilatersl fixation.

The traditional treatment for the femoral shaft fractures in children is closed reduction by continuous traction, usually for 2–3 weeks, until the fracture has achieved partial stability, followed by spica cast immobilization. Fifty three cases, from 3 to 10 years of age, has been treated with closed reduction and immediate application of hip spica csst; all of them were closed fractures of femoral shaft and were not associated with head, abdominal, or vascular injuries. Any angulations in excess of acceptable ranges were corrected with wedging the cast; any overridings in excess of acceptable ranges were corrected by skeletal traction for 1 week, followed by incorporation of the pin to the cast. The resultant overriding and angulation of fragments were within acceptable ranges, and complications were not significant.This method of treatment not only is likely easy in nursing care and comfortsble to the patients but also has some advantages of short stay in the hospital, better utilization of hospital beds, and costsaving. This immediate hip spica cast immobilization seems to be a good method of treatment for the femoral shaft fracture in children.

The goals of orthopaedic management of pelvic ring injuries are to achieve anatomical reduction and secure fixation of fragment and mobilize the patient as early as possible. Previously, pelvic ring injuries have been treated by a wide variety of conservative methods. Their application, however, necessitated a prolonged period of recumbency with associated likelyhood for many complications and did not facilitate accurate reduction and stabilization of most types, resulting in pelvic deformity, non-union and late sacroiliac joint instability. During the past decade, experience with techniques of external and internal fixation of the pelvis has grown and the goals of the methods include provision for sufficient pelvic stability in satisfactory position so that immediate postoperative bed-to-chair transfers can be undertaken and complications due to prolonged recumbency and pelvic deformity can be markedly reduced. We reviewed 47 cases of unstable pelvic ring injuries treated at the depatment of orthopaedic surgery, Dongkang Hospital from January 1984 to December 1987, and the results were as follows ;1. The highest incidence was in the 4th decade and sex ratio between male and female was 1.6:1 2. The most common cause of injury was traffic accident (68.2%) followed by falling down accident (19%) 3. Associated injuries occurred in 28 cases (60%): injuries of the extremities were most common (30%) followed by head injury (13%) and genitourinary tract injury (11%). 4. According to classification of Pennal et al, lateral compression injury was most common (51.1%). Bucholz Group II injury was 57% of all and Group III, 43%. 5. Operative methods, with which 21 cases were treated, were anterior external fixation with AO apparatus or symphyseal plating in Bucholz Group II injuries ; and external fixation, internal fixation (anterior and/or posterior) or both, in Group III injuries. 6. Advantages of operative treatment of unstable pelvic ring disruptions were, by giving stability, early mobilization; easy care of associated injuries, open wounds and nursing; prevention of possible complications of prolonged recumbent position; rapid reduction of pain; and prevention of late complications such as lumbosacral or pelvic pain and gait disturbance.

The author reviewed 148 cases of phalangeal and metacarpal fractures of the hand, excluding distal phalangeal and carpal bones, in 75 patients treated at the Department of Orthopaedic Surgery, Dong-Kang Hospital, from January, 1984 to December, 1987. We obtained the following results ; 1. Better results were obtained in younger patients, transveres or spiral fractures, and cases immobilized in MP joint flexion. 2. Factors that led to worse results included older age, comminuted fracture, wide displacement, intra articular fracture, associated tendon injury, intraarticular pin placement. 3.In case of K-wire fixation, dorsal placement of the wire revealed better result than volar one.

The function of the meniscus and subsequently the importance of meniscus preservation are well known. Thirty-two patients who underwent arthroscopic meniscus repair between 1993 and 1995 were studied retrospectively. Twenty menisci were repaired using modified Henning inside-out technique and the remaining twelve meaisci, outside-in technique. The average delay in surgery was two hundred days. Follow-up was done from 1 year to 3 years (average 22.4 months). The medial meniscus was repaired in 22 cases and the lateral meniscus including two saucerized discoid meniscus in 10 cases. Fourteen patients had anterior cruciate ligament (ACL) tear and other associated knee injuries were lateral condyle fra'cture of femur in one case and lateral condyle &acture of tibia in one case. Assessment of the result was based on the evaluation form of the International Knee Documentation CommitteegKDC). Twenty-seven patients (84.3%) were normal to nearly normal. Abnormal and severely abnormal results were mainly affected by the result of treatment of ACL tear.

To determine the usefulness of MR axial images for diagnosis ACL tears, we reviewed MRIs of 67 patients with ACL tear confirmed by arthroscopic examination, retrospectively. There were 53 acute and 14 chronic tears. The axial MR images had a 97% sensitivity(acute: 96%, chronic: 100%). Findings of acute ACL tears on sequential axial imaging could be categorized as 1) diffuse swelling with abnormal substance signal in 14 cases(27.5%), 2) focal bulging or irregularity of medial border in 11 cases(21.6%) or 3) combination of the two in 26 cases(50.9%). Findings of chronic ACL tears also could be categorized as abnormally irregular thin fibers in 6 cases(42.9%) or nonvisualization(empty lateral wall) in 8 cases(57.1%). We concluded that MR axial images could provide additional useful information in the diagnosis of ACL tear.
